Definitions

  • the present invention is related to a round feeding mechanism for automatic guns, in particular anti-aircraft automatic guns, for feeding rounds in a direction perpendicular to their longitudinal direction from a round compartment, which is located at the one side of the vertical plane containing the barrel of the gun and which can hold a single vertical stack of rounds lying one above the other with their longitudinal directions substantially parallel to the longitudinal direction of the barrel, to a position in the vertical plane containing the barrel of the gun.
  • Said last-mentioned position can then be either a ramming position in the rear prolongation of the barrel, from which ramming position the round can be pushed into the loading chamber in the breech ring of the gun by the ramming mechanism, or an intermediate position, which is located straight above the ramming position and from which the round can be pushed downwards into the ramming position by a special round feeding mechanism.
  • Previously anti-aircraft automatic guns are generally provided only with a single vertical round compartment, which is located in the same vertical plane as the barrel of the gun straight above the ramming position and from which the rounds can consequently be fed directly doWnwards into the ramming position.
  • the round magazine of the gun can be arranged at the side of the vertical plane containing the barrel of the gun, as it will then be possible to provide the gun with two round magazines located on opposite sides of the gun and each one of these round magazines can then comprise one or several vertical round compartments disposed side by side. In this way it will be possible to load the gun with a substantially larger number of rounds than earlier.
  • each one of the'two round magazines located on opposite sides of the gun comprises only one round compartment, the number of rounds which can be loaded into the gun will obviously be twice as large as earlier. Furthermore, it will be possible to load different types of ammunition in the two rounds magazines, whereby it becomes possible to choose and change the type of ammunition rapidly during fire.
  • a round compartment located at the side of the vertical plane containing the barrel of the gun causes, however, certain problems with respect to the feeding of the rounds from the round compartment to the ramming position.
  • the round From the discharge opening of the round magazine, normally the lower end of the round compartment, the round must be moved over a certain distance in a direction perpendicular to the longitudinal direction of the round and to the vertical plane containing the barrel, if the round is to be brought into said vertical plane either directly to the ramming position or to an intermediate position straight above the ramming position.
  • the time available for this traverse feeding of the round is the time from the moment when the recoil movement of the barrel starts to the moment during the recuperation of the barrel, when the ramming of the round is to be started.
  • the down-feeding mechanism for the down-feeding of the rounds from the intermediate position to the ramming position will during a substantial part of the above-mentioned period of time be in such a position that it obstructs the feeding of a new round to the intermediate position from the round compartment.
  • the feeding mechanism for feeding the rounds from the round magazine to the vertical plane containing the barrel of the gun must consequently be very fast and also very accurate with respect to the moment at which the rounds are moved into the vertical plane containing the barrel of the gun.
  • Object of the present invention is therefore to provide a simple and reliable round feeding mechanism for automatic guns for feeding rounds from a round magazine, which is located at the one side of the vertical plane containing the barrel of the gun and which comprises a single vertical round compartment holding a vertical stack of rounds lying one above the other with their longitudinal directions substantially parallel to the longitudinal direction of the barrel of the gun, to a position in the vertical plane containing the barrel of the gun.
  • the round feeding mechanism comprises means, preferably spring means, exerting a permanent downwards pressure on the rounds in the round compartment, a rotatable shaft mounted adjacent the lower, downwards open end of the round compartment substantially parallel to the longitudinal direction of the rounds in the compartment, two star-wheels having spaces between their arms corresponding to the outer diameter of the rounds and being mounted on said shaft with one arm on each star-Wheel projecting into the lower portion of the round compartment beneath and in the way of the lowermost round in the round compartment, whereby one round at a time can be discharged from the round compartment by rotation of the star-wheels and the starwheel shaft about one pitch angle at a time.
  • the round feeding mechanism comprises further rotation checking means for the star-wheel shaft including two, alternatively releasable ratchet and stop devices, each of said ratchet and stop devices having a number of circumferentially evenly spaced stop positions corresponding to the number of arms of the star-wheels and the stop positions of the one ratchet and stop device being circumferentially offset relative to the stop positions of the other ratchet and stop device, and release control means for said ratchet and stop devices actuated by a movable cam path to connected to the recoiling system of the gun for releasing one of said ratchet and stop devices during the recoil movement of the gun and the other ratchet and stop device during the recuperation of the gun.
  • the feed movement of a new round from the round compartment to the vertical plane containing the barrel of the gun will consist of two separate, accurately defined feed steps, the first of which is performed during the recoil movement of the gun and the second during the recuperation.
  • the entire period of time available is used for the feeding of the round, as this is started already during the recoil movement, and it is at the same time made certain that the round is not moved into the vertical plane containing the barrel until this is possible, i.e., at the end of the recuperation of the gun.
  • the round feeding mechanism according to the invention is also comparatively simple in design.
  • the round feeding mechanism comprises preferably a manually operable coupling between the release control means for the rotation checking means of the star-wheel shaft and the cam path connected to the recoiling system of the gun, so that the release control means can be disconnected from said cam path by means of said manually operable coupling.
  • the round feeding mechanism is then also provided with a manually movable cam path for actuating the release control means, when said release control means are disconnected from the first mentioned cam path connected to the recoiling system of the gun.
  • FIGS. 1, 2 and 3 show the round feeding mechanism according to the invention in perspective and partially in section seen from the front and from the left side of the gun.
  • FIG. 1 shows the round feeding mechanism in its neutral position
  • FIG. 2 shows the round feeding mechanism at the beginning of a feed movement controlled by the recoil and recuperation movement of the barrel
  • FIG. 3 shows the round feeding mechanism at the beginning of a manually controlled feed movement.
  • FIG. 4 shows the round feeding mechanism and the round compartment schematically from the rear.
  • FIGS. 5 and 6 show a detail of the round feeding mechanism in section and in two different operating stages.
  • FIG. 7 shows another detail of the round feeding mechanism.
  • FIG. 1 shows the rear end of the barrel 1 of the gun and the breech ring 2. These parts are in the conventional manner located inside a recoil or breech casing not shown in the drawing. Within this breech casing there is a nonrecoiling loading tray 3 located in the rear prolongation of the barrel.
  • This loading tray is assumed to be a socalled shift tongue, which is swingable about a shaft 4 in the breech casing between a lower position, in which the upper side of the shift tongue is serving as a ramming path for a round lying upon the shift tongue, and a somewhat raised position, in which the lower side of the shift tongue can serve as a guide path for an empty shell being ejected from the breech ring.
  • This down-feeding mechanism is of the type described in detail in Patent 3,322,036, wherefore only the down-feeder arm 6, which is swingable in a vertical plane, and the down-feeder 7 mounted on the lower end of the downfeeder arm are schematically shown in FIG. 1.
  • FIG. 1 the down-feeder arm 6 and the down-feeder 7 are shown in the uppermost position, which they occupy at the end of the recuperation of the gun.
  • the down-feeder arm 6 will, as described in detail in the abovementioned patent, swing in clockwise direction in FIG.
  • Two mutually parallel vertical Walls of the breech casing are designated 8 and 9, respectively. These walls are located on opposite sides of the vertical plane containing the barrel 1 of the gun, the shift tongue 3 and the ready position, and the down-feeder arm 6 with the downfeeder 7 and the other parts of the down-feeding mechanism are consequently located between these walls.
  • the wall 8 is forming one side wall in this round compartment.
  • the outer side wall of the round compartment is designated with 12.
  • the inner sides of the walls 8 and 12 facing the interior of the round compartment 19 are provided with guide ribs or similar means guiding the rounds.
  • the lower end of the round compartment is open and in the upper portion of the round compartment there is a spring device 13 shown only schematically in FIG. 3, which exerts a permanent downwards pressure upon the rounds disposed in the round compartment.
  • FIG. 3 the barrel 1, the breech ring 2, the shift tongue 3, the flaps 5, the down-feeder 7, the outer wall 12 of the round compartment and most of the rounds in the round compartment are omitted for the sake of clearness.
  • the rounds are to be fed one by one from the lower, open, discharge end of the round compartment 10 to the ready position on the flaps 5 in synchronism with the firing of the gun.
  • the time available for the feeding of a new round to the ready position is consequently the interval from the moment, when the recoil movement of the barrel starts, to the end of the recuperation of the barrel. It can, however, not be permitted that the new round reaches the ready position until at the end of the recuperation movement, as during the time before that the down-feeder 7 will be in the Way of the new round.
  • the mechanism according to the invention for feeding rounds from the round compartment 10 to the ready position on the flaps comprises two five-armed star-wheels 14 and 15 attached to a shaft 16 mounted for rotation in the breech casing.
  • the shaft 16 is located close to the lower end of the round compartment in the same plane as the wall 8 between the round compartment and the downfeeder 7 and is parallel to the longitudinal direction of the rounds.
  • the star-wheels 14 and have such a diameter that they project partially into the lower portion of the round compartment 10 in such a way that one arm 17a and 17b, respectively, of each star-wheel lies beneath and in the way of the lowermost round 11 in the round compartment 10.
  • the spaces between the arms of the star-wheels correspond to the outer diameter of the rounds.
  • the pitch angle of the star-wheels has such a value that between the lowermost round 11 in the round compartment 10 and the round 11b lying in the ready position on the flaps 5 there is one arm space of the star wheels 14 and 15, in which a round 11a already discharged from the round compartment 10 lies.
  • This round 11a is kept in this position by the star-wheels 14 and 15 and is resting on a number of curved guide plates 18, which are stationarily mounted in the breech casing and extend from the lower edge of the outer wall 12 of the round compartment 10 to the adjacent flap 5.
  • a new round will consequently be moved forward to the ready position on the flaps 5 and a new round be discharged from the round compartment 10.
  • the rounds are fed forward under the pressure exerted by the spring device 13, whereas the rate of feed is determined by the rate, with which the star-wheels 14 and 15 are permitted to rotate.
  • the rotation of the starwheels 14, 15 and thus the feeding of the rounds from the round compartment 10 is controlled by a rotation checking device for the star-wheel shaft 16.
  • This rotation checking device comprises two crown tooth wheels 19 and fixed to the shaft 16 so as to face each other and a non-rotatable, but axially displaceable sleeve 21 disposed coaxially around the shaft 16 between the crown tooth wheels. Both ends of the sleeve 21 are provided with axially projecting teeth arranged to cooperate with the two fixed crown tooth wheels 19 and 20.
  • the sleeve 21 can be displaced in axial direction so that either its one end cooperates with the crown tooth wheel 19 or its other end cooperates with the crown tooth wheel 20.
  • the two crown tooth wheels 19 and 20 fixed to the star-wheel shaft 16 and the axially displaceable sleeve 21 form consequently together two ratchet and stop devices, each having five stop positions, that is the same number of stop positions as the number of arms on the star-wheels 14 and 15. As most readily seen in FIG.
  • the teeth of the crown tooth wheel 19 are somewhat offset circumferentially relative to the teeth of the crown tooth wheel 20, wherefore the ratchet and stop device formed by the crown tooth wheel 19 and the sleeve 21 has its stop positions offset circumferentially relative to the stop positions of the ratchet and stop device formed by the crown tooth wheel 20 and the sleeve 21.
  • a coil spring 22 acting between the sleeve 21 and a fixed spring seat 23 on the shaft 16 so that the spring urges the sleeve 21 towards the crown tooth wheel 20.
  • the sleeve 21 is provided with an upwards projecting arm 22a. At the upper end of this arm a roller 23 is mounted.
  • This roller is running in a groove 24 in a guide member 25 attached to the Wall 8 and this guide member 25 will consequently take up any torques transmitted to the sleeve 21 from the star-wheel shaft 16.
  • the axial position of the sleeve 21 is determined by a fork 26, which has its two arms coupled to taps 27 on opposite sides of the sleeve 21 and which is pivoted about a shaft 28 mounted in the wall 8- perpendicularly to the star-wheel shaft 16.
  • the fork 26 is provided with an upwards pointing rocker lever 29, the upper end of which is coupled to a lever 30 attached to the one end of a shaft 31 mounted for rotation in the walls 8 and 9.
  • the shaft 30 carries an axially displaceable, but non-rotating tooth clutch member 32, which is kept in engagement by means of a coil spring 33 with a corresponding tooth clutch member 34 on a lever 35, which is rotatable on the shaft 31, so that the lever 35 is coupled through the tooth clutch 32, 34 to the shaft 31 and thus to the lever 30.
  • the object of the tooth clutch 32, 34 will be further described in the following.
  • the outer end of the lever 35 is provided with a roller 36 resting against the uper side of the down-feeder arm 6, which is serving as a movable cam path for the roller 36 and thus for the lever 35 for controlling the rotation checking device 19, 20, 21 and thus the star-wheels 14, 15 in dependence of the recoil and recuperation movements of the gun.
  • the round-feeding mechanism described above will operate in the following manner.
  • the down-feeder arm 6 will, as already mentioned and as shown in FIG. 2, swing in clockwise direction so that the down-feeder 7 is moved downwards and pushes a round 1117, which has been fed to the ready position on the flaps 5 at an earlier stage, between the flaps 5 down onto the shift tongue 3.
  • the lever 35 Due to the rotation of the down-feeder arm 6 in clockwise direction it will be possible for the lever 35 to rotate in counter-clockwise direction together with the shaft 31 and the lever 30 so that the rocking lever 29 and the fork 26 can be rotated in clockwise direction about the shaft 28.
  • the spring 22 inside the sleeve 21 can consequently now displace the sleeve 21 towards the crown tooth wheel 20, whereby the sleeve 21 is disengaged from the crown tooth wheel 19.
  • the downwards pressure exerted by the spring device 13 upon the rounds 11 in the round compartment 10 has hitherto been taken up by the arms 17a and 17b on the star-wheels 14 and 15, respectively, which are lying beneath the lowermost round 11 in the round compartment 10, but can now rotate the star-wheels and their shaft 16 in the direction indicated by an arrow in FIG. 2, that is in clockwise direction in FIG.
  • the down-feeder arm 6 is, as already described, swung back in counter-clockwise direction in FIG. 2, whereby the lever 35 is swung in clockwise direction together with the shaft 31 and the lever 30. Due to this the rocking lever 29 and the fork 26 are swung in counter-clockwise direction in FIG. 2 about the shaft 28, whereby the sleeve 21 is moved to the right in FIG. 7 against the action of the spring 22. The sleeve 21 is consequently disengaged from the crown tooth wheel 20 and brought back to its neutral position, in which it cooperates with the crown tooth wheel 19.
  • the shaft 16 and thus the star-wheels 14, 15 can be rotated again by the force from the spring de vice 13 in the round compartment 1t ⁇ , whereby the feeding of the round 11a to the ready position and the discharging of the lowermost round 11 from the round compartment 10 is continued.
  • This feed movement is stopped, when the teeth on the crown tooth wheel 19 due to the rotation of the star-wheels and the star-wheel shaft engage the teeth on the adjacent end of the sleeve 21.
  • the feeding of the rounds is consequently interrupted, when the star-wheels 14 and 15 have been rotated about exactly one pitch angle and thus when the round 11a has been moved forward to the ready position on the flaps 5.
  • the complete feeding movement for a new round to the ready position is consequently divided in two separate, well defined steps, one of which is carried out during the recoil movement of the barrel, whereas the second step is carried out during the recuperation of the barrel.
  • the first feed step consists of a rotation of the star-wheels about an angle of 10 and the second feed step consists of a rotation of the star-wheels about the remaining 62 so that the star-wheels are rotated in total one fifth of one complete revolution, that is about one pitch angle.
  • the invention is of course not limited to only this specific ratio between the magnitudes of the first and the second feed steps, but other ratios can of course be used in other embodiments of the invention.

In this way it is ascertained that the tooth clutch member 32 can be brought into engagement with the tooth clutch member 34, when the fork 39 is swung back to its original position.
  • the manual control means for the round feeding mechanism comprise a bar 44 mounted in guide members 45 on the outside of the wall 8 so as to be reciprocatable in its longitudinal direction.
